We know that 143 is a whole number and that it has to be either prime or composite because all whole numbers other than 0 and 1 are one or the other. So, in order to determine if it is prime or composite, we need to know if any numbers besides 1 and 143 are factors. 1, 11, 13, and 143 are factors so 143 is a composite number.
143 is not prime. 143 = 11 * 13
143 is a composite number because it has more than two factors
Composite.
143 is a composite number because it has more factors than 1 and itself. The factors of 143 are 1, 11, 13, and 143.
Composite. It is divisible by 11 and 13.
143 is composite because it has more than 2 factors. Any number with exactly 2 factors (1 and the number itself) is prime. The factors of 143 are 1, 11, 13, and 143.
143 can be divided by11,which also makes it a composite number :)
143 is composite.
The numbers 2, 13, and 43 are prime. 143 is a composite number. Its positive integer factors, other than one and itself, are 11 and 13.
572 is a composite number, because it is divisible by more than only 1 and itself. It is an even number and thus also divisible by 2. Its factors are 1, 2, 4, 22, 26 143, 286, and 572.All even numbers are composite, except for the number 2.
The number of composite numbers is infinite.
